One mol of KCl is equal to 74.6 grams (from the periodic chart, the gram-atomic mass of potassium is 39.0 and that of chlorine is 35.5.

## How do I calculate moles?

- First you must calculate the number of moles in this solution, by rearranging the equation. No. Moles (mol) = Molarity (M) x Volume (L) = 0.5 x 2. = 1 mol.
- For NaCl, the molar mass is 58.44 g/mol. Now we can use the rearranged equation. Mass (g) = No. Moles (mol) x Molar Mass (g/mol) = 1 x 58.44. = 58.44 g.
